Slackdaddy, welcome to the site!
You will geta lot of good advice here.

I have a whisker biscuit on my bow and love it.
I have 4 inch bohning vanes fletched on my arrow, with a slight offset as well.
One thing I would suggest is to place a dab of glue on the front edge of the vane. This will keep the bristle from getting underneath the vane and pulling off of the arrow.
